WILLIAM DICKS, OF ALBION, *NEW YORK.

MIXER.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed January 6,1906. Serial NoI 294,949.

To @ZZ whom t m/ay concern:

Be it known that I, WILLIAM Dicxs, a citizen of the United States,residing at Albion, in the county of Orleans and State of New York, haveinvented a new and useful Improvement in Mixers, of which the followingis a specification.

My invention relates to improvements in mixers, and more particularly tobread and cake mixers.

The objects of my invention are, first, to provide a simple, durable,and efficient clamp and base for holding the mixers, second, to

rovide a strong bearing for the mixing or ifneading rod, and, third, toprovide means for firmly and simply holding the cover upon thereceptacle.

I attain the objects of my invention by the apparatus shown in thedrawings herewith and made a part of this specification, in which-Figure 1 is a vertical central section of a mixer provided with myimprovement. Fig. 2 is a plan view of my clamping and securing device.Fig. 3 is an enlarged detail section of my improved bearing for themixing-rod, and Fig. 4 is an edge view of the clampingarm 9.

Like characters of reference indicate corre-v sponding parts in thedrawings.

The receptacle 1 is a standard tin pail having a raised bottom 2 and theusual flange 3 It is one of my objects in my clamp construction toprovide means which may thus be used in connection with a pail ofstandard manufacture and form. The pail is provided with a cover 4 andhas the regular mixing-rod 5, which is rotated by the crank 6. The ears7 are of standard construction also.

lVith the well-known parts of the apparatus thus generally indicated Iwill first describe my improved clamping and securing device.

The clamp proper consists of the arms 8 and 9, arranged at right anglesand centrally secured together by a rivet 10. It will be seen byreference to Figs. 1 and 4 that these clamping-arms 8 and 9 arecentrally sprung or dished upwardly and that they rest upon theirextreme ends and clear the table or shelf 11 (see Fig. 1) at theircenter and over their length except at their ends. The arm 8 at itsinner end has an upturned hook or grip 12, which engages over the iiange3. At its opposite end it has a downwardly-bent extension 13, which issecured by rivets to a bracket 14, which has a thumb-screw 15 threadedto it to engage the under side of the table or shelf 11. The bracket 14is further secured to the arm 8 by means 0f a long rivet 16, which meetsthe strain of the thumbscrew 15. The arm 9 has upturned ends or hooks 17and 18, which also engage over the iiange 3, the same as the end 12 ofthe arm 8. A clamping-piece 19 has an inturned or hook end 20 and isadjustably held by a thumbscrew 21, which is threaded into the bracket14 The lower end of this clamping-piece bears against the face of theextension 13 of the arm 8, and its hooked upper end is cap able ofengaging over the flange 3 of the pail.

The operation and object of this part of my invention may new bedescribed. The clamping apparatus is first secured to a table or shelf,as shown in Fig. 1, by the thumbscrew 15. The thumb-screw 21 being wellunscrewed, but not freed from its thread in the bracket 14, theclamping-piece 19 will, by means of the play given by the hole in itthrough which the thumb-screw 21 passes, be released, so that it may beturned to one side of the other to move its hook end 20 out of the way.The receptacle 1 is then slid in, so that the flange 3 engages betweenthe hook ends 17 and 18 of the arm 9, and is finally forced intoengagement with the hook end 12 of the arm 8. The clam ind-piece 19 isnew put in place, so that the rook end 20 engages over the flange 3 andthen the thumb-screw 21 is tightened. This of course firmly clamps thereceptacle by the iiange 3 at four points; but it does more. The strainof the thumbscrew 2]. by reason of its leverage against the extension 13and against the flange 3 tends to straighten out the bend or curve ofthe arm 8, and as the arm 8 is centrally secured to the arm 9 thistendency extends also to the arm 9. This results in bringing the threeends underneath, 12, 17, and 18, down iirmlyupon the table or shelf, sothat the receptacle is not only clamped to the table or shelf, but ismade to rest firmly thereon. Furthermore, the slight spring action thusproduced in the arms 8 and 9 tends to prevent loosening of thethumb-screws 21 or 15 when the apparatus is being used.

Referring now to the second feature of my invention, the properprovision of a bearing for the rod 5 has been heretofore a source ofexpense and trouble, since it has to be secured to the tin cover 5,which is lacking in strength lIO lstated, affords both carrying andsecuring and rigidity. I meet this difficulty in the following simplebut effective manner: I employ a cup-shaped casting or stamping 22, aplate or strip of heavy tin 23, and a bearingtube 24. centrally toreceive the tube 24, and the tin 23 is centrally stamped to receive theend of the tube 24. The top and bottom peripheries i of the tube 24 arethen flanged, as clearly shown in Fig. 3, thus firmly securing the threeparts, and then the tin vplate 23 is soldered to the under side of thecover e. In this manner the use of rivets to secure the periphery of thecup 22 is dispensed with, machining of parts cbviated, and a strongbearing for the rod 5 insured. The use of the plate 23 serves toreinforce the cover e and l overcome its inherent weakness.

Referring now to the third feature of my invention, it is desirable inthis class of devices that means be provided for positively securing thecover down closely over the receptacle. By a modification of the bail Imake it serves the double purpose of affording a handle and also meansfor fastening down the cover. 25 represents the bail in Fig. l, the twobroken ends of which are shown and which will be understood as parts ofa single-wire bail. The ends are bent inwardly, as shown at 26, and thenoutwardly in nearly a straight line, as shown at 27. These straightportions engage through the ears 7 and bear down upon the cover 4,holding it down in place. The bail is readily removed by pressing one ofthe ends inwardly and is thus easily removed and replaced and, as

means Without addition of parts or added cost of manufacture.

Having thus described my invention and its method of operation and use,wI/Vhat I claim is l. In combination with the receptacle, a clamp forholding the same comprising two arms arranged and secured transverselyof each other, hooked ends on said arms to engage said receptacleperipherally at three points, a bracket and means for attaching saidclamp to a table or shelf, and a clamping-piece adjustably secured tosaid bracket to engage said receptacle at a fourth point.

2. In combination with the receptacle, a clamp for holding the samecomprising arms arranged and secured transversely of each other andcentrally bent or (lished upwardly,

scales hooked` ends on said arms to engage said receptacle peripherallyat three points, a bracket and means for attaching said clamp to yatable or shelf, and a clamping-piece ad- The cup-shaped piece 22 isbored jlstably secured to said bracket and means for forcing saidclamping-piece into engagement with said receptacle at a fourth oint andtending to overcome the bend or d1sh of said arms.

3. In combination with the receptacle, a clamp for holding the samecomprising arms arranged and secured transversely of each other andcentrally bent or dished upwardly, hooked ends on said arms to engagesaid receptacle peripherally at three points, a bracket secured to oneend of one of said arms, a thumb-screw in said bracket for sec'uringsaid clamp to a table or shelf, a thumbscrew threaded to said bracket,aclampingpiece taking over said thumb-screw and having one end capable ofengaging the periphery of said receptacle at a fourth point andfulcrumed against said bracket.

Il. In combination with the receptacle, a clamp for holding the samecomprising arms arranged and secured transversely of each other andcentrally bent or dished upwardly, hooked ends on said arms to engagethe flange on said receptacle peripherally at three points, a bracketsecured to one end of one of said arms, a thumb-screw in said bracketfor securing said clamp to a table or shelf, a thumb-screw threaded tosaid bracket, a clamping-piece taking over said thumb-screw and havingone end capable of engaging the periphery of said receptacle at a fourthpoint fulcrumed against said bracket, and a` reinforcing-rivet securingsaid arm and the horizontal part of said bracket.

5. In combination with the cover and the mixing-rod, a bearingcomprising a cup,

shaped casting or stamping, a plate and a tube constituting the bearingproper for said mixing-rod, said tube being flanged or upset over theouter end of said casting or stamping and in and over said plate torigidly secure said cup, tube, and plate together and said plate securedto said cover.

In testimony whereof I have hereunto set my hand in the presence of twowitnesses.
